Network managers are currently faced with the challenge of creating networks that can
provide ultra-fast speed and high performance to serve the needs of todayÕs network
users, while simultaneously preserving the investment they have made in Ethernet and
Fast Ethernet technology.
By addressing the entire spectrum of Ethernet data rates (10/100/1000 Mbps), the
Summit family of LAN switches enables you to introduce high-speed Gigabit Ethernet
backbones into your existing network, while maintaining established connections to the
10 Mbps and 100 Mbps segments that already exist.

ONNECTIONS
The Summit1 provides eight Gigabit Ethernet ports. Six of the ports are Þxed
1000Base-SX ports using 850nm duplex SC connectors. Two of the ports are modular,
and support the standard Gigabit Interface Connector (GBIC). This enables you to select
various types of Þber and copper modules to support longer distances or lower cost.
The Summit1 can be ordered with either two 1000Base-SX or two 1000Base-LX GBIC
transceivers already installed. GBIC transceivers can also be ordered separately.

The Summit2 is a workgroup switch featuring sixteen 10Base-T/100Base-TX ports, two
Gigabit Ethernet uplinks, and one redundant Gigabit Ethernet uplink. The
10Base-T/100Base-TX ports use standard RJ-45 connectors. They are autosensing for
10/100 Mbps operation, as well as half- or full-duplex operation. The Gigabit Ethernet
interfaces support the GBIC connector, and ship with standard 1000Base-SX, 850nm
GBIC modules. Additional cable types are also supported.

FULL-DUPLEX
The Summit Switch provides full-duplex support for all ports. Full-duplex allows
frames to be transmitted and received simultaneously and, in effect, doubles the
bandwidth available on a link. All 10/100 Mbps ports on the Summit autonegotiate for
half- or full-duplex operation.
PORT REDUNDANCY
The Summit2 has an optional redundant Gigabit Ethernet port. Using the redundant
port, you can dual-home the Summit2 to one or two Switches. Figure 1-3 illustrates a
Summit2 dual-homed to two different Switches.
Figure 1-3: Dual-homing configuration
In the event that the active port fails or loses link status, the redundant port is
automatically activated. When the primary port resumes operation, the redundant port
becomes inactive. The redundant port cannot be used for load sharing.
VIRTUAL LANS(VLANS)
The Summit has a VLAN feature that enables you to construct your broadcast domains
without being restricted by physical connections. Up to 255 VLANs can be deÞned on
the Summit. A VLAN is a group of location- and topology-independent devices that
communicate as if they were on the same physical local area network (LAN).
Implementing VLANs on your network has the following three advantages:

Backup Active

¥It helps to control broadcast trafÞc. If a device in VLAN marketing transmits a
broadcast frame, only VLAN marketing devices receive the frame.
¥It provides extra security. Devices in VLAN marketing can only communicate with
devices on VLAN sales using a device that provides routing services.
¥It eases the change and movement of devices on networks. If a device in VLAN
marketing is moved to a port in another part of the network, all you must do is
specify that the new port belongs to VLAN marketing.
For more information on VLANs, refer to Chapter 5.
SPANNING TREE PROTOCOL (STP)
The Summit supports the IEEE 802.1D Spanning Tree Protocol (STP), which is a
bridge-based mechanism for providing fault tolerance on networks. STP enables you to
implement parallel paths for network trafÞc, and ensure the following:
¥Redundant paths are disabled when the main paths are operational.
¥Redundant paths are enabled if the main trafÞc paths fail.
The Summit supports up to 64 Spanning Tree Domains (STPDs).
For more information on STP, refer to Chapter 7.
QUALITY OF SERVICE (QOS)
The Summit has Quality of Service (QoS) features that enable you to specify service
levels for different trafÞc groups. By default, all trafÞc is assigned with the ÒnormalÓ
QoS proÞle. If needed, you can conÞgure some trafÞc to have different guaranteed
minimum bandwidth, maximum bandwidth, and priority.
For more information on Quality of Service, refer to Chapter 8.

IP UNICAST ROUTING
The Summit can route IP trafÞc between the VLANs that are conÞgured as virtual
router interfaces. Both dynamic and static IP routes are maintained in the routing table.
RIP version 1 and RIP version 2 are supported.
For more information on IP unicast routing, see Chapter 9.
NETWORK CONFIGURATION EXAMPLES
This section describes where to position the Summit1 and Summit2 within your
network.
One common use of the Summit is on a Gigabit Ethernet backbone. Figure 1-4 shows an
example of a Gigabit Ethernet backbone within a building.

Figure 1-4: Summit family used in a backbone configuration
The Summit2 on each ßoor is connected to the backbone Summit1 using a 1 Gbps,
full-duplex link. Using Gigabit Ethernet as a backbone technology removes bottlenecks
by providing scalable bandwidth, low-latency, high-speed data switching.
As well as providing a fast-switched backbone between Ethernet LANs, Gigabit
Ethernet-equipped Þle servers and devices may be directly attached to the Summit1,
providing improved performance to the Ethernet desktop.

POWER SOCKET
The Summit automatically adjusts to the supply voltage. The power supply operates
down to 90 V. The fuse is suitable for both 110 V AC and 220-240 V AC operation.
SERIAL NUMBER
You may need this serial number for fault-reporting purposes.
CONSOLE PORT
Use the console port (9-pin, ÒDÓ type connector) for connecting a terminal and carrying
out local out-of-band management.
REDUNDANT POWER SUPPLY PORT
The redundant power supply (RPS) port is used to connect to a Summit RPS. The
Summit RPS provides a redundant power source to the Summit. If the primary power
source for the Switch fails, the Summit RPS takes over, ensuring uninterrupted network
operation.
In addition, when connected to a Summit RPS, the Summit Switch can provide status
on power and fan operation of the RPS through SNMP and the command-line interface.
The Summit RPS can simultaneously provide power for up to two Summit Switches.
